When a compulsorily registrable lease is granted out of registered land and the tenant fails to apply for registration, or its application fails, the lease ‘does not operate at law', per section 27 of the Land Registration Act 2002. Instead, there may be an equitable lease between the parties (see Walsh v Lonsdale), provided that the remedy of specific performance is available to the parties (governed by the usual principle, see Practice Note: Specific performance of property agreements). If specific performance is not available, the court will consider whether a periodic tenancy has arisen in the usual way (see Practice Note: Periodic tenancies). Otherwise, the parties will have no more than a right to sue for
